I’ve noticed the older I get the higher I consider as a minimum altitude and I have fallen in love with twins and biz jets. I’m just waiting when 30 minutes of extra fuel won’t be enough. I can feel it coming. LOL
His opinion was also colored by spending most of his time flying in Northern Arizona, where density altitude is a big big problem. Losing an engine taking off from Flagstaff or Grand Canyon at 7000 feet on a 100 degree day is gonna ruin your afternoon if you’re in a light twin.
